Application led March 1, 1916. Serial No. 81,511.

To all whom t may concern:

Be it known that we, I-IENRY S. ADAMS and JOHN T. MINoHnR, citizens ofthe United States, residing at Viburnum, in the county of Iron and Stateof Missouri, have invented certain new and useful Improvements inStump-Fullers; and we do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

The invention relates to stump pullers, and the primary object of theinvention is to provide a stump puller, which is comparatively simple inconstruction, and includes a portable frame, upon which a shaft isrotatably mounted, for the winding of a cable thereon, for pullingstumps, and further to provide a set of gearings for rotating the cable'carrying shaft and also means for preventing the accidental unwindingrotaq tion of the shaft.

With the foregoing and other objects in view this invention consists insuch novel features of construction, combination and arrangement ofparts as will be hereinafter more fully described, illustrated in theaccompanying drawings and claim.

In describing the invention in detail reference will be had to theaccompanying drawings wherein like characters designate like andcorresponding parts throughout the several views, and in which Figure lis a side elevation of the improved stump puller showing parts thereofbroken away,

Fig. 2 is an edge view of the improved stinp puller showing parts brokenaway, an

Fig. 3 is a detail view of a lever used in connection with the stumppuller.

Referring more particularly to the drawings, 1 designates the portablesupporting structure of the stump puller as an entirety, which includesa pair of runners 2, to the upper surface of the forward ends of whichhooks 3 are attached, for the purpose of hitching a draft animal to thesupporting structure if desired.

The runners 2 have a plurality of standards 4t connected thereto, theupper ends of which are connected by the cross bars 5. The cross bars 5have bearings 6 carried thereby intermediate their ends which rotatablysupport a shaft 7 The shaft 7 carries a gear 8 mounted thereupon, whichgear meshes with a gear 9 carried by a shaft 10. The shaft 10 isrotatably supported by suitable bearings 11, which are in turn supsorted by the central upright or standard 4l. The shaft 10 projectsbeyond the side of the portable structure 1, oppositely from the gear 9,and has a ratchet wheel 12 mounted thereon, which is greater in diameterthan either of the gears 8 or 9. A pawl 18, is pivotally carried by oneof the cross bars 5 for co-action with the ratchet teeth 14 which areformed upon the periphery of the ratchet wheel 12, for preventing theaccidental unwinding rotation of the shafts 10 and 7. The shaft 7 hasone end of a cable l5 connected thereto as is shown at 16, which cableis adapted for winding about the shaft 7, for the purpose of pulling astump. A hook or an analogous grappling device 17 is carried by the freeend of the cable 15. The gear 8, is of greater diameter than the gear 9,so that the speed of rotation imparted to the shaft 10, will bedecreased when imparted'to the shaft 7, and the power thereofconsequently increased. The ratchet wheel 12 has a handle 18 connectedthereto for facilitating the manual rotation of the wheeh The standards4; have blocks 20 attached thereto, which blocks are adapted for formingfulcrums for the lever 21, which is illustrated in Fig. 3 of thedrawings, which lever is employed for pulling stumps which arerelatively hard to pull. In employing the lever 21, it is placed overeither of the blocks 20, and the enlarged end 22 of the same ispositioned in engagement with the square shoulders of any one of theratchet teeth 14 of the ratchet 12, and the lever is pivotally moved forrotating the ratchet and consequently the shaft 7 for winding the cable15 thereon.

In reducing the invention to practice, certain minor features ofconstruction, combination and arrangement of parts may necessitatealteration to which the patentee is entitled provided such alterationsare comprehended within the scope of what is claimed.

What is claimed is In a stump puller, a supporting structure including apair of runners, a plurality of upstanding braces carried by saidrunners, a cable carrying drum rotatably carried by said braces, a shaftrotatably carried by certain of said braces, a ratchet mounted upon saidshaft, a pair of outwardly extending fulcrum blocks carried by certainof said braces below the center of said ratchet, said In testimonywhereof We aiiix our signatures in presence ot two Witnesses.

fulcrum blocks being disposed upon opposite sides of -the center of theratchet, and a HENRY S. ADAMS. lever adapted to be placed upon either ofJOHN T. MINCHER. said fulorum blocks and in engagement with lVitnesses:

one tooth of said ratchet for rotating the Gr. P. BATES,

ratchet upon pivotal movement of the lever. R. A. COUNTS.
